Letters Patent No. 113,199, dated March 28, 1871.

To all whom it may concer/n Be it known that I, STEPHEN' R.No1m1s, of the city, county, and State of N ew York, have invented a new and useful improvement in Oil-Cups for Loose- Pulleys and other 'revolving bodies, or devices, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, and in which` Figure l represents a sectional view of my improved oil-cup as applied to a loose-pulley, and"- Figure 2 a fa'ce or end View of the same.

Similar letters of reference indicate corresponding parts.

My improvement is morev especially designed for the lubrication of loose-pulleys, and the invention consists in a c'up constructed to freely surround the shaft on which the pulley rotates, and connected in concentric relation with the pulley, by which it is driven, and which it` serves to lubricate, by means of a suitable pipe oroutlet within the nave of the pulley, whereby, among other advantages, said cup is free from destroying or interfering with the balance of the pulley. Also, the invention includes a regulating-valve for controlling the discharge, -in combination with the cup constructed as described.

Referring to the accompanying drawing- A represents an oil-cup of cylindrical form,`made in halves, secured or bolted together, for the convenience of structure, t the shaft `on which the loose-pulley that it serves to lubricate is arranged, said cup lying up against the pulley, and between it and a collar on the shaft. Thus constructed and arranged, the oil-cup is made to occupy a concentric relation with the pulley, so that in rotating therewith it does not destroy or impair its balance, as oiland designed to loosely or freely.

cups arranged to form radial projections from the naves of such pulleys do.

Lubricating material is suppliedy to said cup by a screw-cap or nozzle, a, and the discharge is effected by centrifugal motion, as the cup is rotated alongv with the pulley, through a side orifice or teat, '11, or tube, c, fitted therethrough, and arranged to project into the nave of the pulley and form communication with a passage which conducts to the pulleys bearing on its shaft.

The teat b, by its projection into the nave of the pulley, also serves as a driver for the rotation of the cup by the pulley.

i Such modeof supplying the oil is at once certain and effective, and the quantity discharged is or may be regulated by a screw-plugvor valve, d, projected through the periphery of the cup, and made to control the inlet or mouth of. the discharge-tube An oil-cup constructed as described may be readily applied to any pulley, is perfectly secure against spilling, is rapidly fitted to and removed from its place, free from all liability to accidental detachment, and operates most satisfactorily to effect perfect lubrication, without, as before observed, destroying the hang or balance of the pulley. p

What is here claimed, and desired to be secured `by Letters Patent, is

The combination of the driving-teat b, dischargetube c, and screw-regulating plug or Valve d, with the annular oil-cup A, all arranged and' operating essentially as shown and described.
